Three observations:
1. For costing out a system, MSRP is an irrelevant number. I am encouraged by how many people have bought used or at a model closeout, as I did in assembling my systems.
2. No matter whether the system is 4 or 6 digits of expense, part of the fun is seeing how far your budget can take you.
3. (irrelevant) Some years back some economists studied the transaction prices of cameras on eBay. Looking at the unconditional distribution of prices (that is, ignoring which camera it was, etc.) they saw that it had two peaks: One around $200 and another around $800. Of course different people have different needs, and there is a distribution of budgets out there, but nonetheless, why a bimodal distribution. Further research uncovered that the piling up at $200 came about because that is what men thought they could get away with without disclosing price to their wives. The question I wished the OP had also asked is, "How many of you are candid with your spouse about how much you spend?"
